The problem
Too hot in summer? Too cold in winter?
Lightweight construction and big glazed doors make garden rooms wonderful to look at — and difficult to keep comfortable. They can bake in July sun and feel chilly by October.
A garden room should be comfortable in every season.
The solution
Heating and cooling from one system
Modern reversible split air conditioning works as an air-to-air heat pump. A discreet indoor unit and a compact outdoor unit can cool and dehumidify in summer, then provide efficient heating in winter.
Performance depends on the room's insulation, correct sizing, installation quality and external conditions — which is why we assess every building first.

FAQs
Garden room questions
How much will it cost to run?
It depends on the building's insulation, the room size, the system's efficiency, how many hours you use it and your electricity tariff. We can explain the factors for your space, but we won't promise specific figures without assessing it.
Is it noisy?
Indoor units are designed to be quiet, ideal for calls and concentration. Outdoor units make some noise when running, so we position them carefully — particularly near neighbours. Manufacturers publish sound levels for each model.
Does my garden room need to be insulated?
For good results, yes. In a poorly insulated building much of the heating or cooling is lost. We'll assess the walls, roof, floor and glazing and be honest about what's achievable.
Where does the outdoor unit go?
Usually on a wall bracket or ground stand close to the building. We'll discuss space, appearance, drainage, access for servicing and distance from boundaries.
What electrical supply is needed?
The garden room needs a suitable supply with enough capacity for the system. Some buildings need electrical work first — all work must meet the relevant regulations, and we'll flag anything required.
Do I need planning permission?
Many domestic installations fall under permitted development in England, but conditions apply — including unit size, position, proximity to boundaries, listed buildings and conservation areas. Permission isn't always unnecessary, so check with your local planning authority if in doubt.
